How many times this trick would have come in use for me.  I've probably used it all when it came to opening a wine bottle, fork, knife, flathead and etc.  Had I known that my fix for electronics (pounding the hell out of it) worked with a wine bottle with the help of a shoe, it would have saved me a lot of grief.

I'm always late on the discovery end of things, but the moment of ahhhhhhhhhhhhh is still quite magical!
